Psalms 137:9 "Happy is the one who seizes your infants and dashes them against the rocks."

2 Kings 2:24 "He turned around, looked at them and called down a curse on them in the name of the Lord. Then two bears came out of the woods and mauled forty-two of the boys."

Hebrews 9:22 "Without the shedding of blood there can be no forgiveness of sins."

One can always be kind to people about whom one cares nothing.
